Reversible electrodeposition optical modulation device with conducting polymer counter electrode

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
An optical modulation device includes an electrolyte containing electrodepositable metal ions sandwiched between a conducting polymer counter electrode and an optical modulation electrode involving reversible metal electrodeposition. The conducting polymer counter electrode does not generate mobile reactive species, and avoids the light blocking associated with grid or dot matrix electrodes involving reversible metal electrodeposition. A polyaniline counter electrode in a smart window device employing a reversible electrochemical mirror modulation electrode provides high light transmission, fast switching, and coloration to mask the backside of the mirror electrode.
